Roland MC-202 / Alesis Microverb II AC/DC adaptor stuff

Post by rex sole » Wed Dec 20, 2006 8:16 pm

Hi folks.

I've recently picked up an MC-202 alongside a bunch of other bits and pieces (including a dbx 160 compressor which needs a bit of rewiring but looks very juicy), unfortunately missing a power supply. I've scoured the manual and the internet trying to determine what adaptor I should use to power it, but all I can ascertain is that it runs off a 9v supply and not what mA rating I should be using. I've got it running with a 500 mA adaptor without any hitches at the moment, but I still have the nagging feeling I might be damaging it if it only requires, say, a 200 mA adaptor to run. As it's in impeccable condition I don't want to accidently fry the thing, so hopefully someone here will be able to alleviate my fears!

Additionally I have found an Alesis Microverb without a power adaptor, and was wondering again if anyone knew what AC/DC adaptor I should use with this - I'm not so much concerned about breaking this as the 202, but obviously I'd rather avoid breaking bits of gear if at all possible ;)

buy a Boss power supply it should run the Roland MC 202 or a radioshack adapt that has several different settings....

The 202 uses less than a Watt. 800mW according to the manual, which at 9V DC is tiny, about 90mA.

Best to use a regulated supply. This will provide a definite 9v supply no matter how little/much current the unit draws from it. An unregulated supply is cheaper but not a good idea. If you draw only a small current from one, the voltage will rise, maybe harmfully. Spend a couple of extra pounds and get a regulated 9V supply.

Ah, thankfully I am using a regulated supply! I'm surprised that the current it draws is so small, although I guess I shouldn't be if the thing can be run using batteries. Thanks for the speedy responses.

I picked up a handful of regulated supplies from a local parts shop for a few pounds each, some 300mA, some 500. Covers a range of bases then. I also have a couple of 1 or 1.5A too. Handy to have, I think.

Regarding the Microverb, I just checked my Microverb 4, and it takes 9V AC, at 780mA. But that's AC, not DC. Not as easy to find, perhaps...
